Specification of Letters Patent.

Application filed January 11, 1904. Serial No. 188,686.

ed certain new and useful Improvements in Hangers for Type-Bars, ofwhich the following is a specification.

This invention relates to hangers for the type-bars'of type-writingmachines, and has for its object the provision. of a hanger which shallbe simple and inexpensive in construcing a cylindrical platen 22.

tion and furnish a ready means of adjustment for the bearings for thetype-bars.

The invention can be best explained in connection with the accompanyingdrawings, of which Figure 1 is an elevation, partly in section, of aportion of a type-writing machine suIIicient to show the mounting ofahanger and type-bar. Fig. 2 is an enlarged vertical longitudinal sectionof the hanger. Fig. 3 is an enlarged section on the line a b of Fig. 2looking in the direction of the arrow, and Fig. 4 is an enlarged sectionon the line 0 d of Fig. 2 looking in the direction of the arrow.

The frame of the machine (not shown) supports the upper and lowerarc-plates 10 and 11 and a papercarriage (not shown) carryplates aredistributed the type-bars and their accompanying hangers and operatingmechanism in a manner as is well understood, and the type-bar and itsmechanism, which will now be described, are typical of each of them.

The type-bar 19 is hung in a hanger A, secured to the lower arc-plate,said bar carrying a type-head into and out of contact with paper uponthe platen 22, the writing position of the bar being shown in dottedlines,

Fig. 1. To the type-bar is pivoted a con necting-bar 20, which at itsother end is pivoted to the vertically-movable guide-bar 14, mountedbetween rollers 13 in brackets 12. The brackets are secured to thearc-plates, holes being rovided in the bottoms of the brackets an in thearc-plates to permit the passage of the guide-bar. Rigidly secured tothe guide-bar is a key lever or stem 17, which carries the keys 18. Aspring-21 for maintaining the type-bar in inoperative position,

full lines of Fig. 1, is secured to the stem 17 and the upper arc-plate.

The hanger A comprises two vertical plates About the arc- 23andflfiresting uponZthe arclate 1] and secured together by suitableiastenings such as rivets 25, 26, 27, 28, and 29 having shoulders whichbear against the inner face of the plates and separate them by theproperdistance, Fig. 4. Resting upon the plates 23 and 24 is a'securingcap-plate 30, which extends around the arc-plate over the hangers and issecured to the lower arc-plate'by bolts, as shown. At one end of thehanger the plates are tapered, as shown, Figs. 1 and 2,

and in their tapered ends have tapered holes,

Fig. 3, adapted to receive the tapered journals and 36 on the hub 37 ofthe type-bar It), and thereby l'orm hearings on which the bar may swing.All the rivets 25, 26, 27, 28, and 29 act to hold the plates at theproper distance apart; but the rivets 25, 26, and 27 by reason oI' theirarrangement with relation to the bearings of the ty} )e-bar may also beemployed. to adjust those bearings. It will be noted that the rivets arearranged at different' distances from the bearings. If the rivet 27,which is the more remote fastening,

be tightened, plates 23 and 24 will draw across the shoulders of rivets25 and 26 as fulcrums, and the outer ends of the plates will be movedaway from each other, thus loosening the bearings, while if' rivets 25and 26,

which wnstitute the nearer fastening, be-

tightcned the outer ends of the plates will be drawn together, thustightening the bearings. It will be seen-that as the journals of thetype-bars are tapering if they should become worn any lost motion may beovercome by tightening the rivets 25 26 and bringing the ends oi theplates 23 and 24closer together. v

Without limitingmyself to the precise construction and arrangement oi"parts shown and described, I claim 1. In a type-writing machine, thecombination of plates, a type-bar having hearings in said plates, and'lastenings for securing said plates placed at di'Il'erent distancesfrom said bearings, the whole being so constructed and arranged thattightening the fastening- '2. In a type-writing machine, the combinationof dates, a ty e-bar having bearings 1 in said p ates, and 'asteningsfor securing said plates so arranged with relation to said bearings thatwhen one of said fastenings is tightened. the other will act as afulcrum on which said lates rock to loosen said bearings, and wl im thelatter fastening is tightened, the former-will act as a fulcrum on whichsaid plates rock to tighten said bearings, substantially as described.

In a type-writing machine, the combij nation of plates, a type-barhaving bearings in said plates and shouldered rivets for securing saidplates arranged at difl'erent dis tances from said bearings.substantiallyas described.

4. In a type-writing machine, a type-bar hanger comprising two platesand rivets having shoulders engaging the inner faces of the plates forconnecting them in separated relation, said plates having tapered holesnear their ends, combined with a type bar having a hub to fit betweensaid plates and tapered journals projecting from the sides of said hubto fit in said holes, substantially as described.

5. In a type-Writing machine, the con1bination with a type-bar havingjournals pro rivets, substantially as described.

nation with a type-bar having jecting from the sides thereof, of ahanger having side plates provided with bearingsfor said plates atpoints in the same vertical plane, and a single rivet connecting saidplates at a point in a horizontal plane said rivet and in a verticalfrom the type-bar bearings than said rivets, substantially jecting fromthe sides thereof, of a hanger having side plates provided with bearingsfor said journals, a pair of rivets connecting said 30 plates adjacentthe bearings for the journals, and a single rivet connecting said platesat a greater distancelroln the type-bar type-bar earings and in a planebetween the aforesaid 1 +35 6. In a type-writing machine, the cornbi-ijournals projournals, a pair of rivets connecting said 0 between theaforeplane more remote pair of 45 as described.
